Description

Technical Field

[0001] The utility model belongs to the technical field of concrete detection, and particularly relates to a slump detection device for highway concrete. Background Art

[0002] When constructing a highway, concrete is often used. To ensure the quality of the concrete, slump detection of the concrete is required because the slump is an important characteristic of the concrete and has a great influence on the working properties such as the pumpability, plasticization, and spreadability of the concrete.

[0003] Currently, after the slump inspection of the concrete for highway construction is completed, the concrete will cover the inspection device. When cleaning it, it is too difficult. When too much time has passed, the concrete will solidify. When the concrete solidifies, the top of the test plate will be uneven, resulting in deviation in the next test.

[0004] Therefore, we provide a slump detection device for highway concrete. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a slump detection device for highway concrete. By pushing the push rod to drive the scraper to move, and then moving the scraper on the surface of the test plate to clean the residual concrete, it is prevented that the slump cone tilts when the concrete solidifies and falls, resulting in deviation in the next test, solving the problem that when the concrete solidifies, the top of the test plate will be uneven, resulting in deviation in the next test.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a slump detection device for highway concrete, including a cleaning mechanism and a test bench. A stabilizing mechanism is arranged at the top of the cleaning mechanism. A test plate is slidably connected to the inner wall of the test bench. A scraper is slidably connected to the top of the test plate. A push rod is fixedly connected to the top of the scraper. A chute is opened in the inner wall of the test bench. Sliding rods are fixedly connected to the front and back of the test plate.

[0008] The outer surface of the sliding rod is slidably connected to the inner wall of the chute. A positioning groove is opened inside the test bench. Springs are fixedly connected to the inner wall of the positioning groove. There are two springs in total. By pushing the push rod to drive the scraper to move, and then moving the scraper on the surface of the test plate to clean the residual concrete, it is prevented that the slump cone tilts when the concrete solidifies and falls, resulting in deviation in the next test.

[0009] Further, the two springs are symmetrically arranged with the test bench as the center, and the parts included in the outer surfaces of the two springs are the same. A second threaded rod is fixedly connected to the top of the test bench, and an adjusting ring is threadedly connected to the outer surface of the second threaded rod. A benchmark is rotatably connected to the outer surface of the adjusting ring. A slider is fixedly connected to the back of the spring, a connecting rod is rotatably connected to the top of the slider, and a clamping block is rotatably connected to the top of the connecting rod. The test plate is positioned by the clamping block.

[0010] Further, the outer surface of the clamping block is slidably connected to the inner wall of the positioning groove, and the top of the clamping block penetrates through the test plate and extends into the interior. The stabilizing mechanism includes adjusting rods fixedly connected to the top of the test bench. There are two adjusting rods in total, and the two adjusting rods are symmetrically arranged with the test bench as the center. The parts included in the two adjusting rods are the same. The slump cone is pushed upward by the adjusting rods to prevent deviation and partial slump caused by collision with concrete.

[0011] Further, a sliding groove is formed inside the adjusting rod, a limiting rod is fixedly connected to the inner wall of the sliding groove, a support rod is slidably connected to the inner wall of the sliding groove, the inner wall of the support rod is slidably connected to the outer surface of the limiting rod, a slump cone is fixedly connected to the side where the support rods are close to each other, a guiding ring is fixedly connected to the top of the slump cone, and a motor is fixedly connected to the inside of the adjusting rod located on the back. The output end of the motor at the bottom is fixedly connected to a first threaded rod, and the top of the first threaded rod penetrates through the adjusting rod and extends into the sliding groove. Concrete is introduced into the slump cone through the guiding ring.

[0012] Further, the top of the first threaded rod is rotatably connected to the top inner wall of the sliding groove, the outer surface of the first threaded rod is threadedly connected to the inner wall of the support rod, and a sliding rod is fixedly connected to the inner wall of the sliding groove located on the front side. The outer surface of the sliding rod is slidably connected to the inner wall of the support rod. The rotation of the threaded rod drives the support rod to move and drives the slump cone to move.

[0013] The utility model has the following beneficial effects:

[0014] By providing a scraper in the utility model, when the test plate is pulled outward, the clamping block can be squeezed downward, so that the clamping block cancels the limit on the test plate, and the test plate can be pulled out. After the test plate is pulled out, the concrete on its top is removed. After the concrete is removed, there will be some residues on the surface of the test plate. First, push the push rod, and the push rod drives the scraper to move. Then, the residues of the concrete are cleaned by moving the scraper on the surface of the test plate, preventing the concrete from solidifying and causing the slump cone to tilt when it falls, resulting in deviation in the next test.

[0015] The utility model sets a limiting rod. The slump cone is driven to move downward by a supporting rod, so that the bottom of the slump cone contacts the top of the test plate. Then, the concrete is poured into the slump cone through the material guiding ring. After the pouring is completed, the motor rotates reversely, so that the first threaded rod rotates reversely, and the supporting rod moves upward. When the supporting rod moves upward, it drives the slump cone to move. At the same time when the supporting rod moves upward, the limiting rod is used to limit it to prevent the supporting rod from shaking when moving upward, so that part of the concrete collapses, resulting in deviation of the test data.

[0016] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. Brief Description of the Drawings

[0026] Please refer to Figures 1 - 5 As shown, the present utility model is a highway concrete slump detection device, including a cleaning mechanism 1 and a test bench 101;

[0027] A stabilizing mechanism 2 is arranged at the top of the cleaning mechanism 1. A test plate 102 is slidably connected to the inner wall of the test bench 101. A scraping plate 111 is slidably connected to the top of the test plate 102. A push rod 112 is fixedly connected to the top of the scraping plate 111. A chute 109 is opened in the inner wall of the test bench 101. Sliding rods 110 are fixedly connected to the front and back of the test plate 102;

[0028] Furthermore, in the embodiments of the present disclosure, the outer surface of the sliding rod 110 is slidably connected to the inner wall of the chute 109. A positioning groove 105 is opened inside the test bench 101. A spring 106 is fixedly connected to the inner wall of the positioning groove 105. There are two springs 106 in total. When the test plate 102 is pulled outwards, the clamping block 104 can be pushed downwards, so that the clamping block 104 cancels the limit on the test plate 102, enabling the test plate 102 to be pulled out. After the test plate 102 is pulled out, the concrete on its top is removed. After the concrete is removed, some will remain on the surface of the test plate 102. First, push the push rod 112, and the push rod 112 drives the scraping plate 111 to move. Then, the remaining concrete is cleaned by moving the scraping plate 111 on the surface of the test plate 102, preventing the concrete from solidifying and causing the slump cone 204 to tilt during the next use, resulting in deviation in the next test.

[0029] Furthermore, the two springs 106 are symmetrically arranged with the test bench 101 as the center. The parts included on the outer surfaces of the two springs 106 are the same. A second threaded rod 207 is fixedly connected to the top of the test bench 101. An adjusting ring 208 is threadedly connected to the outer surface of the second threaded rod 207. A benchmark 209 is rotatably connected to the outer surface of the adjusting ring 208.

The outer surface of the clamping block 104 is slidably connected to the inner wall of the positioning groove 105. The top of the clamping block 104 penetrates the test plate 102 and extends into the interior.

[0031] Please continue to refer to Figures 1 - 5, the stability mechanism 2 includes adjusting rods 201 fixedly connected to the top of the test bench 101. There are two adjusting rods 201 in total, and the two adjusting rods 201 are symmetrically arranged with the test bench 101 as the center. The parts included inside the two adjusting rods 201 are the same.

[0032] In the adjusting rod 201 of the embodiment of the present disclosure, a sliding groove 212 is opened. A limiting rod 206 is fixedly connected to the inner wall of the sliding groove 212. A support rod 203 is slidably connected to the inner wall of the sliding groove 212. The inner wall of the support rod 203 is slidably connected to the outer surface of the limiting rod 206. A slump cone 204 is fixedly connected to the side where the support rods 203 are close to each other. By moving the support rod 203 downward, the slump cone 204 is driven to move, so that the bottom of the slump cone 204 contacts the top of the test plate 102. Then, the concrete is poured into the slump cone 204 through the material guiding ring 211. After the pouring is completed, the motor 202 rotates in reverse, causing the first threaded rod 205 to rotate in reverse, so that the support rod 203 moves upward. When the support rod 203 moves upward, it drives the slump cone 204 to move. At the same time as the support rod 203 moves upward, the limiting rod 206 is used to limit it to prevent the support rod 203 from shaking when moving upward, resulting in partial slump of the concrete and causing deviation in the detection data.

[0033] A material guiding ring 211 is fixedly connected to the top of the slump cone 204. A motor 202 is fixedly connected to the inside of the adjusting rod 201 located on the back. The bottom output end of the motor 202 is fixedly connected to a first threaded rod 205. The top of the first threaded rod 205 penetrates through the adjusting rod 201 and extends into the sliding groove 212.

[0034] The top of the first threaded rod 205 is rotatably connected to the top inner wall of the sliding groove 212. The outer surface of the first threaded rod 205 is threadedly connected to the inner wall of the support rod 203. A sliding rod 210 is fixedly connected to the inner wall of the sliding groove 212 located on the front. The outer surface of the sliding rod 210 is slidably connected to the inner wall of the support rod 203.

[0035] In summary, a specific usage process of this embodiment is as follows:

[0036] The staff first starts the motor 202. The start of the motor 202 drives the first threaded rod 205 to rotate. The rotation of the second threaded rod 207 drives the support rod 203 to move downward. Then, the downward movement of the support rod 203 drives the slump cone 204 to move, so that the bottom of the slump cone 204 contacts the top of the test plate 102. Then, the concrete is poured into the slump cone 204 through the material guiding ring 211. After the pouring is completed, the motor 202 rotates in the reverse direction, causing the first threaded rod 205 to rotate in the reverse direction, making the support rod 203 move upward. When the support rod 203 moves upward, it drives the slump cone 204 to move. While the support rod 203 moves upward, the limiting rod 206 is used to limit it to prevent the support rod 203 from shaking when moving upward, resulting in partial slumping of the concrete;

[0037] After the slump cone 204 is completely lifted, the slump of the concrete is tested through the reference rod 209. After the inspection is completed and the concrete needs to be removed, the test plate 102 is pulled outward. When the test plate 102 is pulled outward, since the contact between the test plate 102 and the clamping block 104 is arc-shaped, when the test plate 102 is pulled outward, the clamping block 104 can be squeezed downward, causing the clamping block 104 to cancel the limit on the test plate 102, so that the test plate 102 can be pulled out. After the test plate 102 is pulled out, the concrete on its top is removed. After the concrete is removed, there will be some residues on the surface of the test plate 102. First, push the push rod 112. The push rod 112 drives the scraper 111 to move. Then, the scraper 111 moves on the surface of the test plate 102 to clean the residual concrete, preventing the slump cone 204 from tilting during the next use due to the condensation of the concrete and avoiding deviation in the next test.
